MACHINE FOR FORMING BLANK BARS FOR HORSESHOES.

SPECIFICATION forming part of Letters Patent No. 422,564, dated. March4, 1890.

Application filed October 24, 1889- Serial No. 328,095. (No model.)

To all whom it may concern:

Be it known that I, JOHN D. BILLINGS, of the city of New York, and Stateof New York," have invented certain new and useful Improvements inMachinery for Forming Blank Bars to be Used for Horse and Mule Shoes;and I do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part A My object and purpose in this invention areto produce a practical machine which shall by itsdiffercnt-ly-constructed essential parts, when combined and workingtogether, make, form, shape, and produce from iron and steel bars of theproper and required size for horse and mule shoe blanks with calks intheir proper places, or with continuous calks, or made plain with properbends and indentations or holes for nails, and when bent into thedesired shape or contour to be used for horse and mule shoes.

The utility, novelty, and advantages of this invention for forming ironand steel bars of a required size into certain special shapes, and whenbent into the usual forms to be used as horse and mule shoes, over theold and present devices, which are by two or more rolls and by a pass orquick roll movement, are as follows: Instead of rolling the bars by arapid pass movement between the rolls, I make the depressions or spacesbetween the calks and leave the projections in the bar at the necessaryplaces tobe used as calks, and at the same time make the blank shoe-barthus rolled of uniform lengths and the said spaces and calks of uniformlengths and sizes, and also prevent a waste of metal and further preventthe bar when passing through and leaving the rolls from twisting andclinging to the groove in and bending around the roller, and which hasheretofore never been successfully and but imperfectly accomplished. Thebars when heated are placed on the projections or raised die-slots onthe die-plate and they remain in a straight level firm position duringthe passing of the dieplate under the top die-grooved roller, whichlatter acts as the female die, and the die-plate with the raised orprojecting die-slots acting as the male die, the said die-plate and themaking its revolution, being placed or resting at each end upon housingsand held firmly in them, the die-plate passing under the said top rolland carrying the bars the whole length, the top die-grooved roll makingat the same time ,one complete revolution and forming and shaping onecomplete shoe bar or blank, thus effecting the bars by making thedepressions or spaces and leaving the projections in them for the calks,also at the same time making the small depressions for the nail-holes,and all this by arollforged die movement combined. The result of thismanner of forming the bars or blanks is: The calks and spaces'andindentations are of uniformsize, shapes, and lengths, and the I saidbars do not twist nor bend nor cling onto the upper roll, and a waste ofthe bar is also prevented, as all the bars before being heated andplaced on the die-plate are cut off the required length of the shoe-barto be made.

This novel mechanism does away entirely with the under roll, or, inother words, the blank shoe-bar is formed into the detailed shapesrequired for a horse or mule shoe by using one roll, and with theassistance of the said die-plate, which takes the place of the bottomroll.

By this improvement and process horse and mule shoes can be made muchfaster and cheaper and more perfect, and'from one to six shoe-bars ofdifferent kinds of forms-to wit, a threecalked, a four-calked, a plain,a flat, or a continuous-calked shoe-blank, ora shoeblank with series ofcalkscan be made at one and the same time by one revolution of the toproll and passing of the die-plate, as all these several shapeddie-grooves can be made in the top roller, which will form thesedifferent shapes and styles of shoe-blanks.

The invention consists of a movable die plate with a die-grooved orforming roller, between which iron or steel bars are carried and formedinto shapes ready for bending into horse and mule shoes, and themechanism for operating the-same.

Figure 1 is a side elevation of the entire machine. Fig. 2 is a rear endelevation with parts broken to show the gearing arrangement of the dieplate. Fig. 3 is a vertical section on line a 00, Fig. 1. Figs. 4, 5, G,and

7 are modifications of the mechanism for the support and carrying of thedie-plate. Fig. 8 is a detail in section of the die-plate, showing rackand pinion. Fig. 9 is a perspective view of the die-plate. Fig. 10 is anend elevation of the gearing by means of which the die-plate is carriedforward and reversed. Fig. 11 is a detailed section of the die-groovedor forming roller, shown in connection with a rolled bar. Fig. 12 is asection of bar through y y as made for hind shoe. Figs. 13 and 14 areplans of completed bars. Figs. 15 and 16 are views of same bent toproper uhapes. Fig. 17 is asection of bar as formed for front shoe.

A represents the bed 5 B, the houses in which turn the forming-roller 0,running in conjunction with the die-plate D, which is carried by meansof rack E and pinion F. The die-plate D moves with the roller 0 by meansof their connection through the rack E, pinion F, shaft G, and pinionsII and I.

J represents the frames supporting the guide-platesj, against which thewebs Z l work for the purpose of guiding the die plate; K, the rollerupon which the die-plate D moves; L, the driving pulley, which hasconstant motion.

The operation is as follows: The iron or steel bars to be used havingbeen rolled or formed into an approximate shape including the tread orcreasing for the nail-holes and by the usual methods are cut into theproper lengths, then heated and placed upon the raised part a of thedie-plate D while the latter is in its first position, the clutch M isthen thrown into engagement with gear N, which transmits motion throughgearO, roller 0, gears I and II, shaft G, pinion F, and rack E to thedie-plate D, carrying it forward with speed corresponding to that ofroller 0 and guiding the iron into the annular grooves c, which containthe depressions c and projections 0 and 0 which form the calks (Z anddepressions d, and also depressions d for nail-heads. The depressionsand projections in the annular grooves may be made of any form or shapeto produce a blank bar with or without calks or a continuous calk orplain or flat and beveled shape. The bar having been carried through theformer by means of gears O and N, the machine is stopped in position, asshown in Fig. 1, by disengaging the clutch M from the gear S, whichtransmits a quick reverse motion to the gear T through the intermediategear U. The bars are then in condition shown in Figs. 13 and 14:,havingthe fiat face, as in Fig. 12, for hind shoes, or with bevel d, Fig. 17for front shoes. The nail-openings are punched through d and bar bent toperfect shape by an invention already patented on the 25th of December,1877.
